configparser: fix pep8 violations
fix cors problems

ClusterController is a child class of ObjectController
it needs to have the same instance properties
because the instance is created by middleware and not the Proxy Application __init__ was not called with proper arguments
sometimes it worked (because middleware has some properties of Proxy App), sometimes not
now the __init__ is called correctly and all the methods of the parent class should work as expected

cors wrapper `cors_vaidation` was using references to Proxy App in the controller code
when properties were restored `cors_validation` started working as expected

take note, that `test_cors()` test case has some commented out code
it's because of bug in Swift (fixed in current master, cannot really find a specific commit, for some reason) and is not fixed in 1.13.1, which we use for testing and deploy
you can easily test it by checking out `master` and `1.13.1` and running the commented out test on both

use trans-id in opaque networks

using cluster-id in opaque network strings was not that convinient as it is hard to track the request that triggers particular network exchange
now the opaque string will use tx.... transaction id from Swift logs

doc/requests: split paragraphs into real paragraphs

The document had many long lines with single newlines here and there.
I've now separated what looks like differnet paragraphs into real
Markdown paragraphs (separated by two newlines) and rewrapped the
lines to it's easy ot see what belongs where.
